Anceloti bench Modric many times this season and I think that has to do with his age. What's the point of making him play when he can easily sustain injury, he is not as active as before, I think it's right time he pick another club and continue his journey, there are more of young players in the club that are young and can do better than in every way but I respect him for his experience.
It's obvious Modric want to turn the Real Madrid to a family club and loyalty and football doesn't work like that unless he is ready to settle for the position they gave him which is to be assisting as the part of the coach. Who knows one day when Anceloti leave the club, he will replace the coach position just like the way Zidane did back then and his contributions is always remember anytime Real Madrid achievement is been discussed.
Luca Modric is 38, but never underestimate his work ethic for his team, Real Madrid. Currently, as we know, Real Madrid has a stock of midfielders, including two seniors, including Kroos and Luca Modric. However, Ancelotti more often reserves this player from Croatia. This season, Don Carlo only played Modric as the main starter 12 times out of his 25 matches with Real Madrid. in particular, Modric started when one of their young midfielders was injured. that's normal, apart from his age. However, Ancelotti still really needs him as an established player in his team.
This time his role is not only on the field, but on the training ground. His contribution to Real Madrid's young midfielders is enormous. That's why the Croatian midfielder is still with Real Madrid even though his duties are not the same as when he was still heavily relied on. I don't follow developments regarding Modric with Real Madrid, but I would really appreciate it if he really hung up his shoes at Real Madrid. Modric already has everything, he no longer needs to move clubs and play with other clubs in other leagues. moreover, for the Saudi Pro League. he is a Madrid legend, it is natural for him to end his career at the club and team he considers his home and family. as you said, it is possible that Modric will still be part of Real Madrid even though he is no longer a player.
